H 778 Vermont House · 2025-2026 Regular Session

An act relating to dam safety

H.778 requires Vermont's Division of Emergency Management to create emergency response plans (EOPs) for high-hazard dams with significant population at risk: all dams affecting 1,000+ people must have plans by 2030, and those affecting 100-999 people by 2031. The bill also clarifies that the Governor or Emergency Management Director can order evacuations without municipal approval during dam failure risks. Additionally, it mandates a pilot project developing EOPs for two state-owned high-hazard dams with over 1,000 people at risk, due by July 2028. These plans must identify flood zone structures for emergency alerts and include regular training exercises for responders.

MODERATE
The 'As Passed by Both House and Senate' version of H.778 adds an entirely new Section 1 (creating 20 V.S.A. section 52) that mandates emergency operations plans for all high-hazard potential dams in Vermont with specific deadlines, expanding the bill from a limited pilot project into a comprehensive dam safety planning framework. The enacted version only contained a pilot project for two State-owned dams and an evacuation authority amendment, while the passed version layers on mandatory EOP requirements, training obligations, geotagging of structures for alert systems, and five-year exercise mandates.
Scope change
The bill's scope expanded significantly from a pilot project covering two State-owned high-hazard dams to a statewide mandatory framework requiring emergency operations plans for all high-hazard potential dams (State, federal, or private) with populations at risk of 100 or more persons, with binding deadlines in 2030 and 2031.
SCOPE

New Section 1 (20 V.S.A. section 52) creates a mandatory emergency operations plan requirement for all high-hazard potential dams classified by the Department of Environmental Conservation, not just State-owned ones used in the pilot project.

TIMELINE

Deadlines added: EOPs must be completed by January 15, 2030 for dams with a population at risk of 1,000 or more persons, and by January 15, 2031 for dams with a population at risk of 100 to 999 persons.

REQUIREMENT

The Division of Emergency Management must coordinate with dam owners, municipal officials, emergency responders, regional planning commissions, and other interested parties in the inundation zone when developing EOPs.

EOPs must identify alternative routes for emergency responders if public highways or roads are inundated, and copies must be submitted to the Department of Environmental Conservation and each municipality in the area of potential inundation.

The Division must develop training courses, instructional material, and templates that municipalities can use to develop their own EOPs when the Division is not required to do so.

At least every five years, the Division must conduct exercises to practice emergency response under each EOP for high-hazard potential dams, involving all stakeholders and testing communication to emergency responders and public notification.

FISCAL

The Division of Emergency Management is authorized to hire a contractor to complete an EOP required under the new section.

TECHNICAL

For each EOP, the Division must identify structures in the inundation zone where persons would reasonably be expected to live, work, or otherwise occupy, and geotag each structure in the VT Alerts system for dam failure warnings and evacuation orders.
